  The classpath is not the same as the path. It is similar, but a classpath is a set of directories or jar Java files use to search for resources and executable code.

  Assuming you are using the sample file of Start-cache - server.cmd which is supplied with the .net examples to start your server you can put the file tangosol-coherence - override.xml in the C:\Program Files\Oracle\Coherence pour.NET\examples\ContactCache.Java\config directory because it's on the class path when using this script.

• Place an object on the coherence cache

  Hi all
  
  Is there a better way to do the following:
  
  In a region multi-threaded code, I perform the following sequence of steps:
  
  1. use a filter to check if foo object is already in the cache.
  2. If the result of the filter set is null, I perform a lock Cache.lock (foo.getUniqueID);
  3. I put the object foo on the cache Cache.put (foo);
  
  Basically, I try to avoid another thread overwrites the existing cache object.
  
  Is there a better way to do this?
  
  Kind regards
  Ankit

  Hi Pierre,.

  You can use a ConditionalPut EntryProcessor http://docs.oracle.com/cd/E24290_01/coh.371/e22843/toc.htm

  Filter filter = new NotFilter(PresentFilter.INSTANCE);
  cache.invoke(foo.getUniqueID(), new ConditionalPut(filter, foo));
  

  An EntryProcessor aura on a lock implicit button to no other EntryProcessor can run on the same key at the same time. The ConditionalPut will apply the filter specified in the entry (in this case to check that it is not present and if this value is true then will set the specified value.

• A list of names of cache coherence

  Hi all
  How to do to get a list of the NamedCaches which are present in a cluster of consistency at some point?
  
  I couldn't find any API for the same thing, or I could find definitive answers in the forums.
  
  I need the job quite systematic to pre-load my caches at the start, and that's why I need the names of caches configured in my file of coherence-cache - config.Xml.
  
  I have not added dynamically caches, then Yes, I could use a little names encoded hard cache in my initialization routine.
  
  Also, I could analyze my config file to avoid to hardcode the name of cache.
  
  But I was wondering if there is an API for coherence that could help me.
  
  Thank you.

  Hello

  Yes, it's a little bit of chicken and eggs - this is why most of the people don't what already was mentioned above and have some sort of static game constants, either in an Interface or an enumeration that contains the list of all the caches that an application uses. There are more benefits to do that to know what caches you have at the start; all the code accesses one of the same constants for the names of cache, there is no bugs where people use the wrong name and it is easy to change the names of cache. The only place wherever it does not work is in applications where you have caches created dynamically at execution and you do not know the names in front - but then you are unlikely to want to load those at startup.

• Problems upgrading to 12.3.1 coherence incubator

  I am new to the use of consistency. When you try to upgrade v 3.7 and the incubator version correspondent am faced with the question at the start of the server. Indications as to why this would will help me narrow down where I should look.

• Introduction-cache-config with consistency 12.1.2 using?

  In the 3.7.1 version, I used consistency-common incubator library to divide my config of cache files.  This was done with the presentation-cache-config element.

  Example:

  <? XML version = "1.0"? >

  "" < cache-config xmlns: xsi = "http://www.w3.org/2001/XMLSchema-instance"
  "xmlns ="http://xmlns.oracle.com/coherence/coherence-cache-config"
  "" xsi: schemaLocation = "http://xmlns.oracle.com/coherence/coherence-cache-config coherence-cache - config.xsd".
  xmlns:element = "class://com.oracle.coherence.environment.extensible.namespaces.XmlElementProcessingNamespaceContentHandler".
  item: introduction-cache-config = "cache-config - 1.xml, cache-config - 2.xml, cache-config - 3.xml" >

  
  < / cache-config >

  I read that the incubator 12, for version 12.x consistency, will no more support packages associated with this function.

  http://coherence.Oracle.com/download/attachments/14188570/incubator+update.PDF?version=2 & ModificationDate = 1353937318977

  How can I optimize the same cache divided into coherence 12.1.2?

  TKS!

  JP

  Hi JP,

  Now you can!   We have just released an overview of coherence 12.0.0 incubator based on coherence 12.1.2.  This includes support to use the previous namespaces (like element: introduction-cache-config) 12.1.2 coherently.

  The 12.0.0 - SNAPSHOT is now available on: https://maven.java.net/

  The most recent documentation for this snapshot is available here: http://coherence-community.github.io/coherence-incubator/12.0.0-SNAPSHOT/

  We welcome your comments for new version!

  Concerning

• More of a caches(expiry-delay) on the same server for consistency?

  I have a requirement to have two caches in the same server. A delay expires within 60 days and the other with 3 minutes. Is this possible? Please post sample coherence-cache - config.xml and tangosol-coherence - override.xml

  Hello

  It is easily possible to have parameters of different expiry for each of your caches and there are a few ways to do this. You only need to put the configuration in the configuration of the cache file, you don't need to touch the override file.

  The simplest solution is to use different cache with init-params mappings

  
  
  
      
  
          
              cache-one
              sample-scheme
              
                  
                      expiry-time
                      60d
                  
              
          
  
          
              cache-two
              sample-scheme
              
                  
                      expiry-time
                      3m
                  
              
          
  
      
  
      
  
          
              example-distributed
              DistributedCache
              
                  
                      {expiry-time 0}
                  
              
              true
          
  
      
  
  

  So, while that the example above shows how you can pass different parameters for different caches to the regime hiding the example won't work en your condition. The problem is that it is not possible to set a time-out on a cache that is greater than 24 days. That's because consistency keeps the value as an integer (don't ask me why) so he can no longer hold to Integer.MAX_VALUE (2147483647) milliseconds or about 24 days.

  An approach to define a longer maturity is to use the cache.put () method that takes a key, the value of time...

  cache.put(key, value, Base.parseTime("60d"));
  

  .. .well obviously will not if no code does not follow this model to update the cache.

  You could become more complicated and has a custom implementation of a support card that you use for the local cache that would allow the time of expiration for 24 days.

• Problem of memory on 3.7.1.3 coherence

  Hello
  
  Currently, we are migrating on request Ch 3.5.3 to 3.7.1.3. We found that for one of our EntryProcessor process, we reach OOM due 3.7 using more memory. The process I have the following:
  
  We have 3 caches in 2 different services:
  Elements of 120 M Cache1 DistributedCache service
  Cache2 120 M service DistributedCache elements
  Cache3 empty in DistributedCacheIndexing service
  
  
  elements of 120M each and a cache is empty. 90 storage enabled nodes with 4 GB each.
  
  The process task is to load the third cache, which acts as a distributed inverted index, then for each item in one of the 120 M cache of items we carry:
  
  cache1_with_120M.invokeAll (AlwaysFilter.INSTANCE, entryprocessor);
  
  
  the entryprocessor in the processAll of the method traverses all passed through consistency and extract a single field of each object and executes a second entryprocessor (do group by partition, paging, etc.) to the cache3. This call for an another entryprocessor of an entryprocesor is very well since the second goes to another service, and we do not run any other process that might be a dead end.
  
  While this process, it is when the OOM happens only on 3.7.
  
  Using VisualVM allowed us to find that the following objects appear only in 3.7 consume a lot of memory:
  
  PartitionedCache$ storage$ EntryStatus 1.3 M items 126 MB of memory
  BMEventFabric$ EventQueue 1.3 M 76 MB of memory objects
  java.util.concurrent.locks.ReentrantLock$ NonfairSync 1.3 M objs 55MB memory
  java.util.concurrent.ConcurrentHashMap$ HashEntry 1.3 M objs 55MB memory
  java.util.concurrent.ConcurrentHashMap$ HashEntry [of] 4.2 k objs 34 MB memory
  CompositeKey 1.3 M objs 40 MB memory
  RecyclingLinkedList$ Node [15.8 k 31 MB of memory
  java.util.concurrent.locks.ReentrantLock 1.3 M 30 MB memory
  
  Total: 447 MB of memory
  
  (Screenshot of VisualVM difference: https://docs.google.com/open?id=0B7BNexVqvbaqejFFZ1ZWemxqc2s)
  
  What he changed from 3.7 to consume more memory? Is there a way to avoid the extra consumption?
  
  Thanks in advance,
  Mikel.

  Hi Mikel,

  Increase the JVM heap size can also be a solution (although I don't know how much you need) unless you have other reasons to avoid it.

  It is not necessary to run a single at the time partition. You can pack several partitions (for example 10 partitions for each active storage method ~ 10% of your data in a query). Key point does not materialize all key available on particular member set.

  Also recursive entry processor running is not good to be, some eligible items from the GC are kept in the heap while the second entry processor is running.

  Kind regards

• Do not use SOA components custom cache config xml

  I created a Java class to interact with consistency. The class is called using the SISM BPEL. Created a custom config cache file, jared it and added the jar in the classpath library. The composite, has deployed the java class is within a SOA project. After you run the composite, the class is called but joined 'SOADistributedCache' defined in 'fabric-runtime.jar!/soa-coherence-cache-config.xml' instead of joining the 'DistributedCache' defined inside my coherence_config.xml. The soa-coherence-cache-config is configuration by default from cache SOA folder as each join of SCA components. The pot is in server classpath and it overrides the property of my "tangosol.coherence.cacheconfig" system which I'll put in my class.
  Here's my class
  public class CoherenceReader {}
  
  
  public String readFromCache (String key) {}
  
  System.out.println ("before calling cache");
  Dim retVal = (String) cache.get (key);
  System.out.println ("value:" + retVal);
  Return retVal;
  }
  static cache of NamedCache = null;
  
  public static
  {
  System.setProperty ("tangosol.coherence.cacheconfig", "coherence_config.xml");
  System.setProperty ("tangosol.coherence.localport", "8088");
  System.setProperty ("tangosol.coherence.wka", "localhost");
  System.setProperty ("tangosol.coherence.wka.port", "8088");
  Thread thread = Thread.currentThread ();
  ClassLoader = thread.getContextClassLoader () loderPrev;
  try {}
  thread.setContextClassLoader (NamedCache.class.getClassLoader ());
  CacheFactory.ensureCluster ();
  System.out.println ("before call getCache");
  cache = CacheFactory.getCache ("employeecache");
  System.out.println ("cache:" + hide);
  }
  {Finally
  Thread.currentThread () .setContextClassLoader (loderPrev);
  }
  
  }
  }
  
  The result is:

  Simply, you can test this by adding a class inside the SOA project and try to access the cache of it.
  Any help on the use of custom for the SOA components cache configuration?

  Hello

  There are 2 files that you will need to develop/specify for the use of the class from BPEL:

  1 tangosol-coherence - override.xml: this file defines the cluster and it should be created separately for each consistency group. Remember, you must have a different cluster created consistency that is used by the components of SOA deployments and discovery. This file will include all your names of WKA and cluster and so on. You can override all the elements specified in the tangosol - coherence.xml in this file. The file can be loaded using the tangosol-coherence-override system property.

  2 coherence-cache - config.xml: this file is used to specify how data is managed within the cluster? Yet once again, this file must be used to manage the cluster which is called using your BPEL code.

  I am sure that you do not specify the tangosol-coherence - override.xml which makes your BPEL class joining the cluster used by SOA to manage components.

  I hope this helps!

• Read-through Caching with time expired and nearly cache (foreground)

  We are experiencing a problem with our custom CacheLoader and near cache with expiration / delay on the storage card scheme.
  
  I was under the assumption that it was possible to have an expiry time configured on the system of support and that the cache near object was expelled during the backup object has been expelled. But, according to our tests, there must be a delay expires on the regime of front also.
  
  My hypothesis is correct, as there is not an automatic eviction on the cache near (foreground)?

  Hi Jakkke,

  Plan near Cache allows configurable levels of most basic cache coherence cache expiration based versioning of data cache according to the requirements of consistency of the cache invalidation based. Near Cache is commonly used to achieve the performance of the cache replicated without losing aspects of scalability of the replicated cache, and this with a subset of data (based on SRM or UPM) in the of the near cache and all the data in the cache close. Updates of can automatically trigger events to invalidate the entries in the invalidation strategy-based (present, all, none auto) configured for the cache close.

  If you want to expire the entries in the and , you must specify a time-out on the two schemes as mentioned by you in the last example. Now if you are to expire items in the for the reason that they get loaded from the cache-store but remain even keys (only the values should be updated in the cache store), so you should not set the expiration delay on the mention rather the invalidation strategy as a gift. But if you want to have a different set of entries in after a specified delay so that you need to mention this in the configuration of .

  Near cache has the ability to keep the plan before and backup data system synchronized, but the expiration of the entries is not synchronized. Still, avant-regime is a subset of background.

  I hope this helps!

• Oracle coherence first read/write operation take longer

  I'm testing with consistency oracle Java and C++ version and both versions for writing in a local or distributed or near cache first read/write operation take more time compared to the next consecutive read/write operation. What is because of boost operations inside real HashMap serialization or memory mapped implementation. What are the techniques that we can use to improve performance with this first read/write operation?
  
  I'm doing a read operation / written after extraction of the NamedCache Instance. Please let me know if there is any what other stimulant coherence cache of available techniques.

  In that case, why bother with consistency? You're not really winning anything, are you?

  What I'm trying to explain, is that you're probably not going to get this level of performance 'microsecond' on a consistent cluster configuration, running on multiple computers, passes through proxies for clients c ++. Consistency is designed to be a scalable, tolerant cache/processing system and distributed. It is not really designed for real-time, guaranteed processing, micro-nano-second second level. There are much better batteries product out there for this type of treatment if that's your ultimate goal, in my humble OPINION.

  As you say, simply write a small local map (or an array, list, Set, etc.) in a local JVM is always going to be very fast - literally as fast as the processor running on the computer. But this isn't really the development of a product like the consistency. It does not seek to "get the gun" that you can get on a single machine, perform simple processing; Consistency is designed for scalability rather than outright performance. Of course, the use of the local caches (including coherence near caching or replicated caching), can you put some of the performance you ' lost ' in a distributed system, but everything is relative.

  If you wander on some of CUG presentations and attend a few meetings CLOSED user group, one of the first things the support guys will tell you is "spots on a correct cluster' and not 'on a localized development computer. Why? Because the difference in performance and scalability will be huge. I'm not really looking to dissuade you from consistency, but I don't think that it will meet you needs when fully configured in a cluster of "1 Micro seconds for 100000 data collection" on an ongoing basis.

  Just my two cents.

  See you soon,.

  Hi S,

  The first init-param cannot have a id = attribute. The XML code is used to replace the code XML in the tangosol - coherence.xml inside the coherence.jar file and the XML being overloaded without an id for the first init-param attribute you can not have one in your override either.
